About this Poll
Using both RDD landline and cellphone sample from Survey Sampling, SurveyUSA interviewed 800 Oregon adults 10/23/10 through 10/28/10. Cellphones were hand-dialed. Of the adults, 673 were registered to vote. Of the registered voters, 580 were determined by SurveyUSA to be likely to vote in the 11/02/10 general election. Oregon conducts its elections entirely by mail; ballots were mailed to voters 10/15/10. "CPO" = Cell Phone Only, respondents who do not have a home phone and who make and receive phone calls with a cell phone. "Both" = respondents who have both a cell phone and a home phone but for this survey were interviewed on their cell phone by a live operator who dialed the call by hand. "Home Phone" = respondents who were interviewed on their home phone with the recorded-voice of a professional announcer. 26% of the likely voters interviewed for this survey were contacted and interviewed entirely by live operator, 74% of likely voters were contacted and interviewed using recorded voice. CPO respondents account for 13% of likely voters. CPO voters are the least predictable to pollsters. If CPO voters turn-out in smaller numbers than here shown, Democrats will under-perform these numbers, Republicans will out-perform these numbers. Other pollsters show the gubernatorial contest closer than SurveyUSA; some show the Republican ahead. None, to SurveyUSA's knowledge, have included cell phones in their sample.
